La circulación del darwinismo en el Ecuador (1870-1874) (Debates)

En 1871, el jesuita alemán Theodor Wolf comenzó a difundir el darwinismo en el Ecuador a través de las clases de geología y paleontología que impartía en la Escuela Politécnica. Expuso una posición conciliadora del evolucionismo con el catolicismo, en el contexto de un Estado que promovía la cohesión y la identidad nacional a través de la moral católica y las ciencias como vehículo para el progreso. En este estudio se discuten algunos apuntes que atribuyeron estas enseñanzas como la razón por la cual Wolf se separó de la Politécnica y de la Orden Jesuita en 1874, en el marco de una controversia mayor, en la cual el darwinismo fue determinante.

La Baronesa de Wilson en Hispanoamérica: metáforas y un proyecto de modernidad para la mujer republicana (1874-1890)

El presente trabajo analiza las obras de la viajera y escritora española Emilia Serrano (¿1834?-1922) -también conocida como baronesa de Wilson- acerca de América y las mujeres americanas. El método utilizado es la lingüística cognitiva de George Lakoff y de Mark Johnson que se basa en el análisis de las metáforas que el ser humano utiliza para comprenderse a sí mismo y a su entorno social. Se trata de una herramienta para descubrir las convenciones sociales según las cuales un grupo social comprende de un contexto histórico determinado comprende su entorno. El propósito es descubrir las concepciones bajo las cuales piensa la baronesa para describirse a sí misma y a sus congéneres americanas y para lograr insertar a las mujeres en ciertos resquicios del espacio público. El primer capítulo muestra como Serrano contradice a las metáforas que caracterizan a la mujer como un ser de segundo orden. El segundo analiza como Serrano aprovecha el imaginario alrededor de la modernidad católica para promover la importancia de la mujer en el ámbito republicano. Por último, en el tercer capítulo, se explica la estrategia de Serrano para negociar la participación de las mujeres en ciertas ocupaciones públicas sin contradecir la convención social hegemónica que define a la mujer como ángel del hogar doméstico.

La baronesa de Wilson y las metáforas sobre América y sus mujeres, 1874-1890

¿Qué le lleva a una baronesa española de finales del siglo XIX a recorrer sola, en barco, a pie y a lomo de mula, el continente americano desde Canadá hasta la Patagonia en un viaje de más de quince años, y a escribir libros enteros sobre Hispanoamérica y las mujeres hispanoamericanas? ¿Cómo acercarnos a las concepciones de Emilia Serrano (¿1834?- 1922), una viajera católica y de pensamiento conservador? ¿Cómo comprender que esta mujer se exprese en contra de la emancipación femenina por la que abogaban sus pares anglosajonas, al tiempo que apoye la educación de la mujer, su entrada en el mun do laboral y en el debate público? A través del análisis de las metáforas utilizadas por la baronesa de Wilson para describirse a sí misma, a las mujeres latinoamericanas, a las nuevas repúblicas, etc., esta investigación busca en tender las concepciones sociales implícitas en su pensamien to y las estrategias que utiliza para buscar nuevos espacios de expresión para la mujeres republicanas, sin romper con la corriente conservadora a la que se adhiere. Serra no aprovecha el imaginario alrededor de la modernidad católica para resaltar la importancia de la mujer en el ámbito republicano y negocia estratégicamente la participación de las mujeres en ciertas ocupaciones públicas, sin con tradecir la convención social hegemónica que define a la mujer como ángel del hogar doméstico, pero sí aprovechando su potencialidad.

Centennial variations in sunspot number, open solar flux and streamer belt width: 1. correction of the sunspot number record since 1874

We analyse the widely-used international/ Zürich sunspot number record, R, with a view to quantifying a suspected calibration discontinuity around 1945 (which has been termed the “Waldmeier discontinuity” [Svalgaard, 2011]). We compare R against the composite sunspot group data from the Royal Greenwich Observatory (RGO) network and the Solar Optical Observing Network (SOON), using both the number of sunspot groups, N{sub}G{\sub}, and the total area of the sunspots, A{sub}G{\sub}. In addition, we compare R with the recently developed interdiurnal variability geomagnetic indices IDV and IDV(1d). In all four cases, linearity of the relationship with R is not assumed and care is taken to ensure that the relationship of each with R is the same before and after the putative calibration change. It is shown the probability that a correction is not needed is of order 10{sup}−8{\sup} and that R is indeed too low before 1945. The optimum correction to R for values before 1945 is found to be 11.6%, 11.7%, 10.3% and 7.9% using A{sub}G{\sub}, N{sub)G{\sub}, IDV, and IDV(1d), respectively. The optimum value obtained by combining the sunspot group data is 11.6% with an uncertainty range 8.1-14.8% at the 2σ level. The geomagnetic indices provide an independent yet less stringent test but do give values that fall within the 2σ uncertainty band with optimum values are slightly lower than from the sunspot group data. The probability of the correction needed being as large as 20%, as advocated by Svalgaard [2011], is shown to be 1.6 × 10{sup}−5{\sup}.

Bathymetric distribution of the shrimp Rimapenaeus constrictus (Stimpson, 1874) (Decapoda, Penaeidae) in two locations off the southeastern Brazilian coast

The distribution of benthic organisms is directly or indirectly associated with the physical and chemical properties of the water and sediment. This study analysed the spatial and temporal distribution of Rimapenaeus constrictus in unconsolidated sublittoral sediments of two areas off the northern coast of the state of Sao Paulo, Brazil. We also analysed the association of environmental factors with the occurrence of this species. Shrimp were collected monthly from July 2001 to June 2003, with a fishing boat equipped with two double-rig nets, in the regions of Ubatuba (UBA) and Caraguatatuba (CA). The collections were made during the day, along five transects with mean depths of 5, 10, 15, 20, 25, 30, and 35 m. We obtained a total of 5478 individuals, 3403 (UBA = 2025 and CA = 1378) during the first year, and 2075 (UBA = 875 and CA = 1200) during the second year. Significant differences in abundance were observed in relation to depth, season of the year, and also in the interaction between region and depth. Higher abundances occurred in fall and winter, independently of the sampling year. The largest numbers of shrimp were caught on the 20-m transect in UBA and the 25-m transect in CA. It is concluded that the distribution pattern of this species is closely related to environmental factors, and the temperature of the bottom water and the sediment texture were the most significant variables affecting the distribution.

Ecologia alimentar e reprodutiva da piaba-do-rabo-amarelo, Astyanax cf. lacustris (Reinhardt, 1874) (Osteichthyes: Characidae) na Lagoa do Piató, Assu, Rio Grande do Norte, Brasil

The feeding habits and biological aspects of the reproductive cycle of two-spot astyanax, Astyanax cf. lacustris (Reinhardt, 1874) were investigated. Fish samples were captured on a monthly basis, using gillnets of 4 cm mesh size, from the Piató Lake, Assu, Rio Grande do Norte, during the period of September, 2006 to August, 2007. Physico-chemical parameters, such as, temperature, electrical conductivity and dissolved oxygen of the lake were registered. The monthly values of rainfall also were obtained. The 360 individuals captured, were measured, weighed, dissected, and stomach weight and the stage of gonadal maturity were registered. The stomach contents analyses were carried out based on volumetric method, points, frequency of occurrence and applying the Index of Relative Importance. The degrees of repletion of the stomachs were determined besides the Index of Repletion relating to feeding activity variations and frequency of ingestion with limnological parameters and rainfall. The food items identified were separated into distinct groups according to their origin. Sex ratio and Gonadosomatic Relation of females were verified to determine the spawning period and fecundity. The physico-chemical parameters presented the following annual mean values: temperature = 28.8ºC, electrical conductivity = 992.5 µS.cm-1; dissolved oxygen = 4.9 mg.L-1 during the study period. The annual mean of the rainfall was 63.5 mm. The results indicate that this species present an omnivorous feeding habit with a tendency towards insectivory, with an increase in feeding activity during the dry season. The aquatic oxygen to interfere very importance in the feeding activity than the others factors physico-chemicals of water and rainfall. There was a predominance of females, with a sex proportion of 1M:7F. The macroscopic characteristics of the ovaries and testicles revealed four stages of gonadal development: immature, maturing, mature and spent. A temporal variation was observed for the gonadal development of males and females. There was reproductive activity through out the year, with peaks in the months of February, April and June to correspond with the rain of precipitation of the region. The mean fecundity was 7.681 mature oocytes, varying from 4.476 to 12.036, with mean of 7.681. There was positive relation between fecundity and body mass. Condition Factor is not an efficient indicator of the reproductive period of this species. The species A. cf. lacustris is an opportunist and is well adapted to the conditions of the semi-arid Caatinga Biome

O desenvolvimento do psiquismo na vida cotidiana: aproximações entre a psicologia de Alexis N. Leontiev e a teoria da vida cotidiana de Agnes Heller

Este trabalho pretende apontar algumas aproximações entre a psicologia de Leontiev e a teoria da vida cotidiana de Agnes Heller, mais precisamente aquilo que a filósofa húngara denomina como formas de pensamento, sentimento e ação típicas da cotidianidade. Nossa hipótese é a de que esse estudo pode trazer contribuições para a psicologia sócio-histórica, especialmente no que se refere à compreensão das características do psiquismo humano numa sociedade marcada por processos de alienação, isto é, quando a estrutura da vida cotidiana cerceia o desenvolvimento intelectual, afetivo e moral dos indivíduos. Pretendemos, assim, contribuir para o entendimento daquilo que denominamos de psiquismo cotidiano.
